Densest k-Subgraph Approximation on Intersection Graphs
We study approximation solutions for the densest k-subgraph problem (DS-k) on several classes of intersection graphs. We adopt the concept of -quasi elimination orders, introduced ...

An FPTAS for Flows over Time with Aggregate Arc Capacities
We study flows over time in networks with transit times on the arcs. Transit times describe how long it takes to traverse an arc. A flow over time specifies for each arc a time-dep...

The Train Delivery Problem - Vehicle Routing Meets Bin Packing
Abstract. We consider the train delivery problem which is a generalization of the bin packing problem and is equivalent to a one dimensional version of the vehicle routing problem ...

The Power of Uncertainty: Bundle-Pricing for Unit-Demand Customers
We study an extension of the unit-demand pricing problem in which the seller may offer bundles of items. If a customer buys such a bundle she is guaranteed to get one item out of i...

Online Ranking for Tournament Graphs
We study the problem of producing a global ranking of items given pairwise ranking information, when the items to be ranked arrive in an online fashion. We study both the maximizat...

Satisfiability Modulo the Theory of Costs: Foundations and Applications
Abstract. We extend the setting of Satisfiability Modulo Theories (SMT) by introducing a theory of costs C, where it is possible to model and reason about resource consumption and ...

Preemption Sealing for Efficient Concurrency Testing
The choice of where a thread scheduling algorithm preempts one thread in order to execute another is essential to reveal concurrency errors such as atomicity violations, livelocks,...

Assume-Guarantee Verification for Probabilistic Systems
Abstract. We present a compositional verification technique for systems that exhibit both probabilistic and nondeterministic behaviour. We adopt an assume-guarantee approach to ver...

Efficient Detection of Errors in Java Components Using Random Environment and Restarts
Software model checkers are being used mostly to discover specific types of errors in the code, since exhaustive verification of complex programs is not possible due to state explo...
